Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

    Back Office Switch, 10/100/1000 Mbps, 24-Port


    Quick Facts

  • Access 24 Gigabit Ethernet, Fast Ethernet, or Ethernet devices through your office network.
  • Provides enhanced QoS support for real-time applications.

    • Further Details

  • Four ports on each switch also support Gigabit fiber uplinks with an SFP Optical Transceiver.
  • Port mirroring enables you to isolate network errors without disrupting data flow.
  • Add a Gigabit fiber uplink with an SFP Optical Transceiver.
  • Port- and tag-based VLAN.
  • Bandwidth aggregration is ideal for high-volume communications.
  • Ports autosense for speed and autonegotiate for duplex.

    Looking to grow your office network the smart way? BLACK BOX® Back Office Switch enables you to connect to up to 24 Gigabit Ethernet, Fast Ethernet, or Ethernet devices.

    What’s more, you can populate four switch ports with the optional Small Form Factor Pluggable (SFP) Optical Transceivers and connect to fiber-based Gigabit Ethernet!

    The switch has the management capabilities network administrators need. Simply access a switch via your Web browser and log on to monitor, configure, and control each port’s activity.

    In addition, the Back Office Switch supports Quality of Service (QoS), port mirroring, tag- and port-based VLAN, and bandwidth-aggregation capability.

    Put some fiber in your data diet.
    The last four ports on the switch are dual-media ports that give you the option to connect to fiber-based Gigabit Ethernet. Add one of our three Small Form Factor Pluggable (SFP) Optical Transceivers (sold separately) for short-, medium-, or long-distance fiber optic connections. The transceivers are hot-swappable and available in multimode and single-mode versions. They are Layer 1 devices, which makes them transparent to your application.

    Keeping it real time.
    This switch not only supports Layer 2 802.1p Priority Queue control, but it also provides enhanced QoS support for real-time applications like Voice over IP (VoIP). And it supports Layer 4 TCP/UDP port and ToS classification.

    Mirror, mirror on the port.
    Port mirroring copies traffic from one specific port to a second target port. This mechanism enables you to track network errors or abnormal packet transmissions without interrupting the flow of data. All ports on the Back Office Switch is capable of port mirroring.

    The traffic report.
    You can use VLAN to isolate traffic between different users and thus provide better security. Plus VLAN enables you to confine the broadcast traffic to the same VLAN broadcast domain to boost network performance.

    Life in the fast lane.
    The switch enables you to combine ports to create a multilink, load-sharing trunk. Port trunks are useful for switch-to-switch cascading, which provides very fast, full-duplex speeds for high-volume communications.

    With this switch you can set up to 16 ports per trunk. This switch supports up to 24 trunking groups.

    All ports are autosensing for speed and autonegotiating for duplex. The switch's Auto MDI/MDI-X feature means you never need a crossover cable. Furthermore, the switch supports IEEE 802.x flow control for full-duplex mode and collision-based backpressure for half-duplex mode.
